Application filed March 26, 1909. Serial No. 485,988.

To all whom it may concern:

lie it known that I, DANIEL McKenzie, a citizen of the United States,residing at Narren, in the county of Trumbull and State of Ohio, haveinvented a new and useful Machine for Making Molds; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappcrtains to make and use the same.

This invention, about to be set forth and claimed, belongs to the art ofmold making machines, and it primarily pertains to a machine by whichmolds for forming pipe fittings may be formed.

The object in view is the provision of a structure for forming molds bywhich pipe fittings may be cast of various configurations, and which maybe applied to machines as are now used in practice.

Another object of the invention is the production of new and novel meansfor supporting and operating the several parts of such 'tlllilpptll'tltlls.

Another object as aimed is to facilitate the making sinrhmolds, and toproduce a structure which is simple in design and rather inexpensive tomanufacture.

Another object of the invention is the provision of a frame work havinga vertically movable member provided with partially rotatable members,of one or more designs for making impressions in the sand or othermaterial of the molders flask, for the formation of pipe fittings withor without flanges.

Another object of the invention resides in the provision of means forrotating or operating the said rotatable members.

A further object of the invention is to provide means whereby thevertically movable member may be raised and lowered, and when raised, itmay be held in such position.

The features and elements which constitute the above entitled invention,may be changed and varied, that is to say, in an actual reduction topractice, if, however, the changes and variations are covered by theappended claims.

To obtain a full and correct understanding of the details ofconstruction, combinations of features, elements and advantages,reference is to be had to the hereinafter set forth description and theaccompanying drawings in connection therewith, wherein Figure 1 is aperspective view of the apparatus embodying the features of theinvention, and showing the vertical movable member in a raised position.Fig. 2 is a top plan view of the device. Fig. 3 is a sectional view uponline 3--3 of Fig. 2. Fig. t is a sectional view on line -tl of Fig. 3.Fig. 5 is a perspective view of plastic material showing the impressions8, 10 and 18. Fig. (i is a sectional view through two impressionssimilar to that shown in Fig. 5 placed in registration, and designed forsupporting the core for forming the hollow portion of the fitting, aboutwhich the molten metal is poured. F 7 is a detail view of one of thedisks 9.

in regard to the drawings, wherein similar reference characters indicatecorresponding parts in the several illustrations, 1 designates the frameof the apparatus, which is shown as being rectangular in contour, butthe applicant; desires it to be umlerstood that any form of frameworkmay be utilized in practice. This framework is provided with suitablesupports 2, which are reinforced by suitable bracing members 3 and t,the bracing members 3 being shown preferably as being integral with thesupports 2, while the bracing member 41- is secured to the bracingmember 3 by suitable screws or other means The supporting members 2 andthe framework 1 are secured together also by suitable screws or othermeans (i, as shown clan-1y in Figs. 1 and T designates a body member,which forms the impression S in the sand or other malcrial. in order toform the body of the fitting, as shown clearly in the drawings. Thetitling, as shown in the drmvings, is to be of the form of a T joint,but it is to be understood that elbow joints or other joints or fittingsof any design or configuration may be readily molded.

9 designates the partial rotatable members, which are for the purpose offorming the impressions 10 in sand or other material, as shown in Fig.5, in order to form the fittings of various configurations. The member 7is rcmovably attached to and carried by the vertically movable member11. This vertically movable member is provided with slots 12 and 13,which cross one another, as shown in Fig. .1-. The member 7 has screwsor other suitable means 14 penetrating therethrough and extended throughthe slot 12, and to their threaded extremities 15, the plates 16 areattached, they being positioned at right angles to the slot 12, as shownclearly in Fig. 4, so as to prevent upward displacement of the member 7.

Carried by and secured to the vertically movable member 11, are thecore-prints 17, which are placed adjacent to the outer faces of themembers 9. These core-prints 17 are designed for the purpose of formingthe impressions 18, in the sand or other material, as shown in Fig. 5,for the support of the core 19, shown in Fig. 6, about which core, themetal 20, when in a molten state, is poured.

The members 9 are disk shape, as shown, and are cut away for a slight,distance toward their centers, and substantially half way about theirperipheries. The purpose of forming the members 9, in this manner, is toallow their positions to be changed, in order to form impressions, bywhich fittings may be formed with flanges of various configurations, asshown in Fig. 6. To change the positions of the members 9, shafts orrods 21 are provided, which are mounted in suitable bearings 22, of thebracket members 23. These bracket members 23 are secured to the underface of the vertically movable member 11, as shown clearly in Figs. 3and 4, by means of screws or other suitable means 24. These shafts orrods are provided with cranks and handles 25, and pinions 26. Thesepinions 26 mesh with the gears 27, which are carried by stub shafts 28of the members 9, and are journaled in suitable bearings 29, between thecore-prints and the upper surface of the vertically movable member 11.The core-prints are hollowed out, as shown at 30, in order to make roomfor the gears 27. The rotatable members 9 upon their outer faces areprovided with depressions 31, which are designed for the purpose ofreceiving the extremities of the slidable rods or shafts 21, that is tosay, when the members 9 are held in one or another position. Surroundingthe shafts or rods 21 are collars 32, which are held to the shafts orrods by screws or bolts 33, as shown clearly in Figs. 3 and 4.Interposed between the collars and one of the bearings of the bracketmembers are coiled springs 34, whlch surround the shafts or rods, andperform the functions of holding the rods or shafts in engagement withthe impressions or sockets 31. By drawing the rods or shafts outwardlyagainst the tension of the spring 34, they may be disengaged from thesaid impressions or sockets, as will be clearly apparent.

To guide the vertically movable member, when being raised, movable guidemembers are provided, which are adjustable with relation to thecooperating guide members 36, by means of the screws or other suitablemeans 37. The screws 37 are threaded in apertures 38 of the downwardlyprojecting extensions 39, which are as shown as being integral with theframework 1 of the apparatus. The cooperating guide members 36 aresecured by screws or other suitable means 40 to the under face of thevertically movable member 11, as shown in Fig. 4.

To raise the vertically movable member 1.1, a frame 41 is secured to theunder face thereof, by screws or other suitable means 42, and isprovided with a downwardly eX- tending guide rod 43. This guide'rod 43moves and is guided in the apertures 44, of the transverse brace member4, as shown clearly in Figs. 1 and 2. Mounted in bearings of the frame1, is a shaft 45, from which an arm 46 radially projects, to which a.link 47 is pivoted. This link 47 is pivoted to the frame 41 by means ofthe screw, pin or other means 48, as shown clearly in Fig. 3 of thedrawings. The link 47 is so pivoted between the frame 41 and the arm 46,that the pivot 49, between the arm and the link, is positioned out ofalinement of the center of the shaft and the pivot 48, when thevertically movable member is in a raised position, in order to lock thesaid vertically movable member in. such a position, as shown in Figs. 1and 3.

To form pipe fittings of the design shown in Fig. 6 the partiallyrotatable members are set or dispcsed in the positions shown in Fig. 1,after which one-half of a molders lask (not shown) containing wet sandor other plastic material is placed upon the frame 1 of the apparatus.lVhile this half of the flask is in such position, the verticallymovable member 11 is moved upward, in order that the body member, therotatable members 9 and the core-prints 17 may make the impressions 8,10 and 18 in the said material, after which the vertically movablemember is again moved downward.

To raise and lower the vertically movable member 11, the shaft 45 ispartially rotated in. one direction or the other by means of the handlecarried thereby, shown in Fig. 1. The shaft as before stated is providedwith the arm 46, which has connections with the frame 41 (which projectsdownwardly from and is carried by the vertically movable member 11)through the medium of the link 1 7 causes the vertically movable memberto be raised and lowered by the rocking of the shaft hen the verticallymovable member is being raised or lowered, the same is guided duringsuch movement by means of the guide members 35 and 36, shown clearly inFigs. 1 and 4.

hen it is desired to rotate the members 9 in order to present aperiphery of a different configuration, the shafts or rods 21 are drawnoutward. in order to disengage t making impressions to cast the body ofa fit with the sockets ill (the collars 3Q acting against the tension ofthe s 'irings 3 1-) after which the shafts or rods 21 are partiallyrotated, and by the cooperation of the intermeshing gears 26 and. 27(which are carried by and rotatable with the shafts or rods 21 and the.stub-shafts 28) the rotating members t) are operated, in order topresent the desired periphery. When the shafts or rods 21 are beingdrawn outwardly, the gears 26 and 97 remain in engagement with oneanother, for the reason that the gears 27 are of greater thickness, aswill be clearly apparent from Fig. 3. Each time the rotatable membersare changed, the vertically movable member 11 is in its lowermostposition, and after the members 9 are changed the member 11 is againraised, in order to cause the flange forming members 9 to make theirimpressions in the sand for other plastic material. As will be observedthe pattern member 7, the members 9, the mean for operating the members9, and the core-prints, as well as the frame 41 and the rod 43 are allmovable with the vertically movable member 11, as one body.

To change the design of the impressions 8, 1t) and 18, the partiallyrotatable members 9 are rotated by the handles 25, so that the portionsopposite the portions shown in Fig. 1., face upward, after whichimpressions are formed in the material of the'two halves of a molderstlask.

Any design of rotatable members may be employed in connection with theapparatus shown in the drawing, so that various forms of impressions maybe formed whereby arions forms of fittings may be molded.

From the foregoing, the essential features, elements and the operationof the device, together with the simplicity thereof, will be clearlyapparent.
